:12 Finn TATES PATENT FRINGINIGQ MACHINE.

SPECIFICATION forming part of Letters Patent No. 647,100, dated April10, 1906.

Application filed May 13,1899.

To aZZ whom it may concern:

Be it known that I, SAMUEL KROSS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Fringing-Machines forthePurpose of Preparing Woof for Bugs and Mats, of which the following is aspecification.

My invention relates to the manufacture of rugs and carpets from old andworn carpets and other suitable fabrics. In the utilization of old stockit is necessary to cut the material into narrow strips and ravel outboth edges of the strip, leaving several threads uncut in the middle ofthe strip to hold the fringe in place while being woven into the rug.

The object of my invention is to provide a machine that will enable theoperator to pass the strips through the machine and cut the threads ofwarp on each edge at short intervals, thus leaving the short particlesof warp to be easily shaken out in the process of weaving. The fringe ismore even and less frayed than when prepared by the old method, and itis possible to manufacture a better grade of goods at a less cost thanheretofore. I attain this object by a mechanism illustrated intheaccompanying drawings, in which- Figure 1 is a vertical view of theleft-hand side piece of the frame, showing the cutter and roller incross-section and the clampingjaws with screw. Fig. 2 is a verticalfront view of the upper part of the machine, showing all parts. Fig. 3is a horizontal plan view in section, cut on line 8; and Fig. at is aview of a piece of woof after it has been through the machine.

The frame consists of two vertical side pieces A A, provided withclamping-jaws I), having a hand-screw c in the lower jaw. The sidepieces are secured to each other by bolts 6 and are fixed to the benchf, as shown in Fig. 1. A metallic rollerB is formed the required sizeand is keyed to a shaft 9. Apertures g are drilled in the frame, adaptedto receive the journals'g on the roller. Two

similar steel rings 71. h, having a series of teeth or knives h fixedtransversely on the periphery at a required distance apartcircumferentially and provided with apertures and keyways 1', adapted toreceive the shaft j, are formed. A washer 7t, Fig. 3, of any requiredSerial No. 716,738. (No model.)

thickness and smaller in diameter than outters is formed, adapted toslip on the shaftj, and is placed between the cutters h. The object ofthe washer is to provide a space for the uncut warp in the strip, andthe width may be regulated by a thinner or thicker washer. An annularringl of the same out side diameter as the cutters and thinner than thewasher k is placed loosely on the washer 7c. The object of this ring isto prevent the fibers from the strip from clogging the teeth. Twomovable boxes m, having apertures adapted to receive the ends of theshaft j, are fitted in mortises n, Fig. 1, so that the teeth on thecutters will rest on the roller. Two set-screws 0, having jam-nuts p,are placed vertically in the top of the frame-pieces A, with the lowerends resting against the boxes m. These screws regulate the pressure ofthe cutters on the roller. A table q is fixed to the front of frame,provided with two guides r, held in place by screws arranged to move inslots 5. Gear-wheels 7, t, arranged to cause the roller and cutters totravel at a uniform speed, are fixed to the ends of the shafts, one ofthe shafts being longer than the other, adapted to receive a crank c, ora pulley if it is desired to use power.

To use this machine, clamp it to the bench or table, cut the fabric instrips the required width, set the guides r to fit the strip to befringed, start an end into the machine on top of the roller and underthe cutters, regulate the pressure just suficient to cut through thefabric, and turn the crank as fast as desired. When the strip has beenrun through, give it a shake and the cut warp or threads will fall out.This need not be done, however, as it can be woven into the rug andbeaten out afterward.

I do not wish to confine myself to cutting and fringing old carpet-stockor to preparing filling or woof for rugs, since my machine may be usedto fringe new fabrics for other purposes than rugs. Neither do I claimthe revolving toothed cutters broadly, since they are in use in manycutting-machines; but

What I do claim, and wish to secure by Letters Patent, is-

In a fringing-machine, the combination of the shaft j provided with twoannular rings having a series of knives fixed radially and transverselyon the periphery, the smooth roller adapted to rotate with and engagethe to rotate loosely on the outer surface of said said knives; theshaft g arranged to carry Washer, the gear-wheels rotating the knives 10said roller, one end of the shaft overhanging and smooth roller inunison, substantially as the frame provided with a gearwheel and adescribed.

5 crank, the gear-wheel fixed to the shaft j SAMUEL KROSS.
